Writing the interval [2,6] using​ set-builder notation, is:

{ x | x ∈ R, 2 ≤ x ≤ 6 }

Real numbers (R) include all rational and irrational numbers.

Thus If we need to write the interval [2,6] using​ set-builder notation, we will write as:

{ x | x ∈ R, 2 ≤ x ≤ 6 }

This is interpreted as x belongs to a set of real numbers greater than or equal to 2 but less than or equal to 6

First: combine like terms

3 - 5w + 12 + 2w - 3

(-5w) + 2w = (-3w)

Second: subtract 3 from 12 (12 - 3)

3 - 3w + 12 - 3

Third: subtract 3w from 3 (3 - 3w)

3 - 3w + 9

Forth: add 9 to w (w + 9)

The piecewise function for the monthly charge W(x) for a customer who uses x hours of electricity is given by:

The graph of the function is given at the end of the answer.

A piecewise-defined function is a function that has different definitions, depending on the input of the function.

For this problem, we have that:

The monthly charge is calculated differently according to the number of kWh of electricity used, divided into two cases as follows:

For up to 300 hours, the base charge of $50 plus the hourly fee of $0.0650 is charged, hence:

W(x) = 50 + 0.0650x, 0 ≤ x ≤ 300.

For more than 300 hours, the customer is charge 50 + 300 x 0.0650 = $69.5, plus the hourly fee of $0.0850, hence:

W(x) = 69.5 + 0.0850x, x > 300.

Parking space B covers a greater area.

Here, we are given a parking lot has two types of parking spaces- rectangles and parallelograms, as shown in the figure.

Let us calculate the area of each figure one by one-

Area of rectangle = length × breadth

Here, length = 6 units

breadth = 3 units

Thus, area of rectangle = 6 × 3

= 18 square units

Now, area of a parallelogram = base × height

here, base = 4 units

height = 5 units

Area = 4 × 5

= 20 square units

⇒ the area of the parallelogram is greater than the rectangle

Thus, parking space B covers a greater area.

Your question was incomplete. Check for the missing figure below.

The width of the rectangular painting painted by John is  24.15 inch.

For, the given question;

The perimeter of the rectangular painting painted by the John is 108.56 in.

The formula for the perimeter of the rectangle is;

Perimeter = 2(length + width)

Thus,

2(length + width) = 108.56

The rectangular painting is 5.97 in. taller than it is wide.

It means;

Length = 5.97 + width

Put the value in perimeter.

2(5.97 + width + width) = 108.56

11.94 + 4 width = 108.56

width = 24.155

width = 24.155 (decimal rounded to two decimal places)

Therefore, the width of the painting is 24.15 inch.

Consider the equation,

y = x + 5

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept.

In equation y = x + 5, the graph y = x is shifted 5 units towards the negative x-axis.

To graph the equation we determine various points on the line.

When x = 0,

y = x + 5

y = 5

When y = 0,

y = x + 5

0 = x + 5

x = - 5

When x = - 1,

y = x + 5

y = - 1 + 5

y = 4

When x = - 2,

y = x + 5

y = - 2 + 5

y = 3

When x = - 3,

y = x + 5

y = - 3 + 5

y = 2

Therefore, the points on the line y = x + 5 are ( 0, 5), (- 5, 0), ( - 3, 2), ( -1, 4) and ( - 2, 3).

The non-permissible replacement for x in this expression is 1.

An expression is a set of terms combined using the operations +, – , x or ÷. An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An expression is in simplest form when no terms can be combined.

Given:

The given expression is

[tex]x=\frac{b^{2} }{5b-5}[/tex]

Non-Permissible Values: values of a variable that make the denominator of a rational expression equal 0.

If the denominator contains a binomial, the non-permissible values can be determined from the factored form of the binomial.

A rational expression is a fraction, where p and q are polynomials, q ≠ 0. A non-permissible value is a value of the variable that causes an expression to be undefined. For a rational expression, this occurs when the denominator is zero.

Inadmissible Values: values of a variable that do NOT make sense in the context of a given problem.

According to given question we have

The expression is

[tex]x=\frac{b^{2} }{5b-5}[/tex]

By definition, the non-permissible replacement for x in this expression, is the value of x that makes the denominator equal to zero.

5b-5=0

5b=5

Divide both sides by 5 we get,

b=1

Therefore, the non-permissible replacement for x in this expression is 1.
